Ubuntu Security Podcast: Episode 224

"It’s been an absolutely manic week in the Linux security community as the news and reaction to the recent announcement of a backdoor in the xz-utils project was announced late last week, so we dive deep into this issue and discuss how it impacts Ubuntu and give some insights for what this means for the open source and Linux communities in the future."

Ubuntu Portugal Podcast: Episode 293 - A Microsoft salvou o Linux

"Não, não é uma mentira de 1 de Abril (até porque gravámos no dia 2). A semana foi agitada, plena de arreliações e polémicas; o mundo ficou de pernas para o ar com o "backdoor" XZ; um funcionário da Microsoft salvou o Linux; a Canonical meteu ordem nos snaps de criptomoedas; o Miguel perdeu a paciência com séries do Japão Feudal que o levaram a experimentar Debian Bookworm em Raspberry pi; alguém abriu um bug no Bugzilla, o Diogo tem um brinquedo novo com botões que já está no carrinho de compras; e no meio disso tudo ainda tivemos tempo para fazer as malas a caminho da Wikicon em Évora."

"The big story right now is the recently uncovered backdoor in liblzma (aka XZ) – a relatively obscure compression library that happens to be a dependency of OpenSSH.
This incident is noteworthy for so many reasons: the exploit itself, how it was deployed, how it was found, what it says about our industry & how the community reacted. Let’s dig in!"
